My husband and I have been TTC for 7 months now .We have actively had unprotected sex since we then . I was expecting my cycle to start on Tuesday but it did not show up , so naturally I'm excited because I feel like we have a good chance this time . Today I went to the bathroom and when I wiped my self (sorry TMI) a very light colored blood was on the tissue . It has been like this all day of and on . I don't see any blood on the pad just when I wipe ( which I mentioned already that it is very light and very minimal ). Could this be implantation bleeding ?
